Corporate Updates

NEWS RELEASE

International Lithium Corp. End of Quarter Update

Vancouver, October 04, 2021. The board of International Lithium Corp. (the “Company” or

“ILC”, TSX Venture: ILC) is pleased to announce an update on progress at the end of the quarter

Sale of Mariana

This sale of ILC’s remaining 8.58% stake in Litio Minera Argentina and the remaining rights in

the Mariana project to ILC’s partner Ganfeng Lithium for CAD$ 16.8 million was announced on

September 21, 2021. The Mariana transaction counts as a “Reviewable Disposition” under TSXV

policies and is subject to TSXV approval and shareholder approval by a majority of the shares

entitled to vote on the transaction. The Company is pleased to announce that it has now obtained

TSXV approval to close the transaction following it obtaining the overwhelming support of the

largest shareholders who provided the required shareholder approval. The Company expects to

close the transaction in mid-October following the Chinese National Day and Golden Week

holidays.

Convertible Debentures

All the remaining convertible debentures which were due to mature on September 30, 2021 were

converted prior to maturity, resulting in the issue of an additional 10,600,000 shares and the

elimination of C$ 530,000 of convertible debt.

Shares in issue

Following the exercise of warrants for CAD$ 600,000 mentioned in the September 21, 2021 news

release, and the conversion of CAD$ 530,000 of convertible debentures mentioned above, the

Company now has 233,880,443 common shares in issue. A new Fact Sheet reflecting this is

available on the company’s website.

Raleigh Lake progress

The Company commenced the autumn program at its 100% owned Raleigh Lake lithium and

rubidium project in Canada last week. The Raleigh Lake project now consists of over 17,000

hectares (170 square kilometres) of mineral claims in Ontario, and is regarded by ILC

management as ILC’s most significant project in Canada. The exploration conducted to date

covers only 5% of ILC’s current claim area that has already shown significant quantities of

rubidium and caesium in the lithium bearing pegmatite. Raleigh Lake is 100% owned by ILC, is

not subject to any encumbrances, and is royalty free. It has perfect infrastructure being close to

the town of Ignace and the city of Dryden, Ontario and is transected by the Trans-Canada

Highway, high power electrical lines, gas pipelines and the Canadian Pacific Railway.

The recently mobilized field crews will continue exploration in Zones 1 and 2 of Raleigh Lake.

Drilling in this area has delineated laterally extensive dykes of lithium-bearing pegmatites that dip

gently for several hundred metres and remain open in several directions. A bio-geochemical

orientation survey is being conducted to ascertain if the technique can be applied to the

remainder of the project area where there is less outcrop and surface exposure of underlying

geology is poor. The Company is widening the lithogeochemical sampling coverage by extending

beyond the original 3000 Ha of claims, which will capture Zone 5, where the potential for

pegmatite mineralization similar to the Tanco deposit at Bernic Lake, Manitoba, still exists. Due

to the expansion of ILC’s claims from 3,000 to 17,000 hectares this summer, there will also be

some preliminary prospecting carried out over the newly staked areas for evidence of both lithium

and nickel sulphide mineralization.

There is more work to do to get to a useful resource estimate at Raleigh Lake given also the

large amount of additional claims acquired, and the Company will be doing this in a commercially

sensible order, with a maiden resource estimate within Zone 1 now expected in 2022.

Avalonia progress

ILC’s joint venture in Ireland with Ganfeng Lithium has seen continued drilling during the summer,

and has made good progress in obtaining a clearer picture of the structure of the pegmatites

there. The Company hopes to be able to publish results from the Avalonia project in the next

couple of months.

Summary

This has been a very significant quarter for the Company, and the coming quarter is also

expected to be an active one. Additional exploration at Raleigh Lake will form the bulk of the

Company’s operational expenditure in the next quarter. At the same time the Company will also

look for additional exploration opportunities.

About International Lithium Corp.

International Lithium Corp. believes that the ‘20s will be the decade of battery metals, at a time

that the world faces a significant turning point in the energy market’s dependence on oil and gas

and in the governmental and public view of climate change. Our key mission in the new decade

is to make money for our shareholders from lithium and battery metals while at the same time

helping to create a greener, cleaner planet. This includes optimizing the value of our existing

projects in Canada and Ireland as well as finding, exploring and developing projects that have

the potential to become world class lithium and rare metal deposits. In addition, we have seen

the clear and growing wish by the USA and Canada to safeguard their supplies of critical battery

metals, and our Canadian Raleigh Lake property is strategic in that respect.

A key goal has been to become a well funded company to turn our aspirations into reality, and

following the disposal of the Mariana project in Argentina in 2021, which is the subject of this

announcement, we believe we are well placed in that respect.

International Lithium Corp. has a significant portfolio of projects, strong management, and strong

partners. Partners include Ganfeng Lithium Co. Ltd., (“Ganfeng Lithium”) a leading China-based

lithium product manufacturer quoted on the Shenzhen and Hong Kong stock exchanges (A share

code: 002460, H share code: 1772) and Essential Metals Limited, quoted on the Australian Stock

Exchange (ASX:ESS).

The Company’s primary strategic focus is now on the Raleigh Lake lithium and rubidium project

in Canada and on identifying additional properties.

The Raleigh Lake project now consists of over 17,000 hectares (170 square kilometres) of

adjoining mineral claims in Ontario, and is regarded by ILC management as ILC’s most significant

project in Canada. The exploration there so far, which is on only about 5% of ILC’s current claims,

has shown significant quantities of rubidium and caesium in the pegmatite as well as lithium.

Raleigh Lake is 100% owned by ILC, is not subject to any encumbrances, and is royalty free.

Complementing the Company’s rare metal pegmatite property at Raleigh Lake, are interests in

two other rare metal pegmatite properties in Ontario, Canada known as the Mavis Lake and

Forgan Lake projects, and the Avalonia project in Ireland, which encompasses an extensive 50-

km-long pegmatite belt.

The ownership of the Mavis Lake project is now 51% Essential Metals Limited (ASX: ESS, “ESS”)

and 49% ILC. In addition, ILC owns a 1.5% NSR on Mavis Lake. ESS has an option to earn an

additional 29% by sole-funding a further CAD $8.5 million expenditures of exploration activities,

at which time the ownership will be 80% ESS and 20% ILC.

The Forgan Lake project will, upon Ultra Resources Inc. meeting its contractual requirements

pursuant to its agreement with ILC, become 100% owned by Ultra Resources (TSXV: ULT), and

ILC will retain a 1.5% NSR on Forgan Lake.

The ownership of the Avalonia project is currently 55% Ganfeng Lithium and 45% ILC. Ganfeng

Lithium has an option to earn an additional 24% by either incurring CAD $ 10 million expenditures

on exploration activities by September 2024 or delivering a positive feasibility study on the

project, at which time the ownership will be 79% Ganfeng Lithium and 21% ILC.

With the increasing demand for high tech rechargeable batteries used in electric vehicles and

electrical storage as well as portable electronics, lithium has been designated “the new oil”, and

is a key part of a “green tech” sustainable economy. By positioning itself with projects with

significant resource potential and with solid strategic partners, ILC aims to be one of the lithium

and rare metals resource developers of choice for investors and to continue to build value for its

shareholders in the ‘20s, the decade of battery metals.
